Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a reinforcement structure when upper and lower columns have variable cross-sections. Background Art

[0002] External steel cladding is a widely used method for reinforcing concrete components. It usually uses steel sections or steel plates to cover the surface, four corners or two sides of the original component, and high-strength cement mortar or epoxy resin slurry is poured between the surface of the concrete component and the external steel cladding. At the same time, transverse plates or hoops are used as connectors to improve the overall load-bearing performance of the reinforced component.

[0003] However, when using the method of steel-wrapped columns, the core area of ​​the beams and columns is often reinforced by using angle steel vertically passing through the floor slab. However, when encountering columns with variable cross-sections, this reinforcement structure is difficult to implement. Therefore, a reinforcement structure for the upper and lower columns with variable cross-sections is proposed to solve the above problem. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a reinforcement structure when the upper and lower columns have variable cross-sections, which can improve the construction efficiency, economy and safety of steel-wrapped columns.

[0005] The technical solution for achieving the purpose of the utility model is: a reinforcement structure when the cross-sections of the upper and lower columns change, including angle irons arranged at the corners of the columns, the outer side of the angle irons being fixedly connected with a gusset plate, the gusset plate being L-shaped and located below the crossbeam, a plurality of stirrups being arranged in the angle irons of the core area frame beam, the stirrups passing through the angle irons on both sides and being welded and fixed, and the angle irons of the upper column and the lower column are fixedly connected with Z-shaped short steel bars on the same side.

[0006] In some embodiments, the stirrups are located in the area below the beam plate, and the stirrups pass through the entire frame beam and are welded and fixed to the angle iron.

[0007] In some embodiments, the Z-shaped short steel bar is provided on each side of each angle iron and is welded to the angle iron on one side. The angle iron of the upper column and the angle iron of the lower column are fixed by the Z-shaped short steel bar, and the Z-shaped short steel bar runs through the beam and slab.

[0008] Compared with the prior art, the present invention has the following significant advantages:

[0009] The utility model connects the angle irons with the beams and columns by glue injection or other conventional methods, welds a plurality of gusset plates to ensure their posture, then opens holes at the core frame beams, arranges stirrups in the holes, passes the stirrups through the entire frame beams, and welds the stirrups to the angle irons to form closed stirrups; then, according to the cross-sectional deviation of the upper and lower columns, opens holes at corresponding positions of the floor slabs to allow the Z-shaped short steel bars to pass through, and welds the Z-shaped short steel bars to the angle irons, which can solve the problem of external steel reinforcement of columns at variable cross-sections, thereby improving the economy and safety of external steel reinforcement construction of upper and lower columns with variable cross-sections;

[0010] The invention solves the problem that the upper and lower column reinforcement structures are difficult to connect and fix when the upper and lower columns have variable cross-section structures encountered in the existing steel-clad column construction. BRIEF DESCRIPTION OF THE DRAWINGS
